4:betterFiveIconDock
Our favorite and most frequently used apps are in the iPhone dock, so this tweak is a no-brainer as it allows you to add an additional icon to the iPhone dock. The five icons in the dock looks great on the iPhone 6s Plus and iPhone 6s as the icons are well spaced out, and doesn’t look cramped as on the iPhone 5/iPhone 5s (you can always fix that reducing the size of the icons).
5:f.lux
We’ve all been there – a notification arrives on your iPhone late at night, and the screen brightness nearly blinds you for the first few seconds after unlocking. F.lux aims to solve this problem by adjusting the color of your iPhone’s display to better adapt to the time of the day.
6:BlurryLaunch
BlurryLaunch displays a smooth blur effect when launching the App Switcher.

Control Center by default has a restricted set of toggles including ones for Airplane mode, Wi-Fi, Bluetooth, Do Not Disturb. CCSettings increases the set of available toggles by adding toggles for Cellular Data, VPN, Personal Hotspot, Location Services, Auto Lock and a lot more.

To see the additional list of toggles, you just have to swipe from right to left. In landscape mode, you’ll have to swipe vertically. You can also customise the order and remove or add toggles from Settings > CCSettings.
8:BetterFourByFourFolders
BetterFourByFourFolders lets you put 16 apps in a single folder.

This tweak will give you the ability to blur your badges. It also makes the badges transparent, so whatever color your wallpaper is, it assumes that color and blurs it. You can also add different color borders and border thicknesses to your badges within the settings.
